Oculus Hand Tracking

“Hand tracking” via link is considered a developer feature by Meta, so there’s a few hoops you need to jump through.

This is only tested with a Quest 2 and a Quest Pro. It probably doesn’t work with a Rift S.

  1. Enable hand tracking in your headset - documentation
  2. Set up your account as an Oculus Developer account - documentation - you do not need to allow USB debugging or install the ADB drivers
  3. Restart the Oculus PC software
  4. Enable ‘Developer Runtime Features’ under Settings -> Beta. If you don’t see the option yet, try again later - it can take a few hours
  5. In HTCC settings, set ‘hand tracking source’ to ‘OpenXR Hand Tracking’

Developer Runtime Features option

Virtual Desktop

Virtual Desktop is not supported; you must use Link or AirLink instead. This may change in the future if Virtual Desktop gains support for OpenXR and OpenXR hand tracking.

Sleep/wake

Hand tracking and gesture recognition is not perfectly reliable; it will hopefully improve with future Oculus firmware updates.

HTCC reduces the changes of accidental clicks by:

  • adding sleep/wake mode
  • ignoring gestures unless you’re looking close to your hand

‘Wake’ hand tracking by waving your hand close to the center of your view. Tracking will ‘sleep’ for that hand after a few seconds of little movement.

The limits can be tweaked in the registry if needed.

FAQ

Why do pinch gestures require Oculus headsets?

The [XR_FB_hand_tracking_aim] OpenXR extension is required, which is currently only supported by Oculus headsets.

Other headsets would work if other OpenXR runtimes add support for XR_FB_hand_tracking_aim, or if other projects emulate it using [XR_EXT_hand_tracking] or vendor-specific APIs. I am not aware of any projects doing this at present.

Standard OpenXR hand tracking via XR_EXT_hand_tracking does not provide enough similar precise gestures.
